Thermal overload relay is a more common and more economical one, overload protection device. Especially forSingle-phase asynchronous motorThe bimetal sheet is the working component of the thermal motor overload relay. Today, Senli Motor Xiaobian will take you to understand the topic of thermal protection.
What is the winding thermal protection? In the case of bimetallic sheet thermal overload relay, it is a mechanical device that converts temperature into mechanical displacement, because this bimetal is composed of two metal sheets with different thermal expansion rates, and it is installed inSingle-phase asynchronous motorIn the circuit, the current through the motor will flow through the metal trip element.
Because it is made of two metal sheets with different thermal expansion rates, when the flowing current heats the bimetal sheet, the different thermal expansion characteristics will cause it to expand at different speeds. If the temperature is higher than the ambient temperature, the bimetal will bend in one direction, and the relay will be opened at a specific temperatureSingle-phase asynchronous motorThe current is cut off, and the circuit shuts down.
Single-phase asynchronous motorThermal overload relays have a class division known as the trip class, with different grades indicating the response time under overload conditions. The thermal overload of bimetal sheets is relatively cheap and does not need to be high-The level control can work, but there is little response to temperature increases until it is completely turned off.
